Inspect the strain relief frequently to make sure it is firmly attached and intact. Keep cables properly wound around the pole stems and protect them during use. Floppy, pinched, or snagged cables may short, causing erratic noises or unnecessary replacement of the searchcoil. Sweep the searchcoil carefully, especially when using around rocks and building foundations and avoid hitting the searchcoil against hard, solid objects and surfaces. Keep your searchcoil slightly off of the ground during the sweep especially when using in gravel or hard, rocky dirt. Always use a properly designed protective scuff cover on the searchcoil. Remove and clean out scuff covers periodically to avoid buildup of mineralized dirt particles which will affect performance. The searchcoil is waterproof and can be submerged in either fresh or salt water. After the searchcoil is used in salt water, rinse it and the lower stem assembly well with fresh water to prevent corrosion of the metal parts. The searchcoil is waterproof but the electronics are not, so always prevent any moisture or water from entering the control housing and never allow the cable connectors to become submerged in water. If working in or near water, or if there is a possibility of rain, use a protective weather resistant pouch or plastic bag to cover the control housing. Make sure it can breath in order to ensure against condensation buildup inside. After each use, clean the detector with a soft cloth to remove dust, moisture, or other contaminants. When transporting the detector in a car during hot weather, store it on the floor of the passenger compartment if possible. Using a carry bag gives additional protection. In any case, never allow the detector to roll around unprotected in the trunk or back of a pickup truck. Protect your detector from dust, moisture, and extreme temperatures during storage. When shipping, use the original factory carton or similar heavy-duty container, and provide a minimum one inch of padding around all parts. Treat your detector as you would any sensitive electronic instrument. Though ruggedly constructed and designed to withstand the demands of normal treasure hunting, proper care is essential. 23

5 22 LASER RAPIER II OPERATOR INSTRUCTION MANUAL CONTENTS 3 GENERAL INFORMATION CARE AND USE Basic Care The Rapier II is a sturdy instrument, but it is not designed to withstand abuse. In caring for your Rapier II, there are several important DO NOTs to remember. DO NOT use it to pry rocks loose or to beat bushes out of the way. DO NOT drop the machine into water. DO NOT use it unprotected in the rain. DO NOT leave it exposed at night where dew could form on it. DO NOT store it in places that could be extremely hot (next to a woodstove, in an attic). DO NOT leave it in the truck of a car or in the back of a hatchback style car where high temperatures could build up. DO NOT store it with the battery installed as batteries may leak. DO NOT spray lubricants such as WD-40, or any type of cleaner, solvents, sealants or other chemicals into or onto the electrical parts, switches or controls. And finally, DO NOT attempt to modify or repair the detector s electronics as this will void your detector s warranty.

You can help avoid this from happening to your detector by following these basic care and protection guidelines. Operate your detector exactly as recommended in this OPERATROR INSTRUCTION MANUAL. Use only high-quality alkaline batteries of the correct voltage. Never substitute a different voltage. When using a Ni-Cad battery always use a separate convertible pack with the proper voltage output for the detector s design. Remove the battery from the detector after each use. This will prevent damage to the detector if the battery leaks. The INDEX OF COMMON QUESTIONS on page 25 is a quick reference that guides you to the page containing the answers to some of the more common questions new metal detector owners have.

6 4 LASER RAPIER II OPERATOR INSTRUCTION MANUAL OPERATING TECHNIQUES 21 INTRODUCTION To be successful in treasure hunting with a detector you must: Use a high-performance metal detector designed for the type of treasure hunting you will be doing. Learn how to use your metal detector properly. Search where there is buried treasure to be found. Be persistent. The Rapier II was designed for coin hunting, competition hunting and all-purpose use. This multifunction detector is very powerful, yet very easy to use. This OPERATOR INSTRUCTION MANUAL is designed to help you learn to operate the detector properly for maximum performance in various search conditions. Complete instructions on how to operate the Rapier II are found in the two main sections: GETTING STARTED and OPERATING TECHNIQUES. If you are new to metal detecting, we highly recommend reading and following the entire GETTING STARTED section to develop the feel of your detector. Then, study and practice the OPERATING TECHNIQUES. If you are an experienced detectorist and are familiar with the concepts of metal detecting, you may want to go directly to the OPER- ATING TECHNIQUES section. Whatever your prior detecting experience is, the more skilled you become at operating this detector, the more rewarding your results will be. If you are new to treasure hunting with metal detectors, keep in mind that if there are no valuable metal objects buried where you are searching, it won t matter how good your metal detector is or how skilled and persistent you are. To learn more about where to search for valuable buried metals, check with your detector dealer or bookseller for magazines and books on treasure hunting. RECOMMENDED RECOVERY METHOD Adapted from Tools N Techniques By Robert H. Sickler PLUGGING Used only where allowed in natural wooded areas and very moist lawn areas. Plugging in hard dry ground can damage grass roots, leaving yellow dead spots in time. After pinpointing target, cut three sides of a four-inch cube around target center using a six-inch sturdy hunting knife (Fig. 1A). Cutting a hinged cube rather than a cone shaped plug will properly orient its return, prevent removal by a lawnmower, and lessen the chance of scratching the target. With the knife blade, carefully pry against the cube side opposite the hinge (uncut side) and fold back (Fig. 1B). Scan searchcoil over plug and hole to isolate target location. If target is in plug, carefully probe until located. If target is in hole and not visible, probe bottom and sides until located and remove (Fig. 1C). Repeat scan for additional targets. Replace all loose dirt with plug. Seat plug firmly with foot (Fig. 1D). Figure 1A Figure 1B Figure 1C Figure 1D

7 20 LASER RAPIER II OPERATOR INSTRUCTION MANUAL Finally, raising the searchcoil during pinpointing can also help by narrowing the response to the target. Practice pinpointing often, and you will soon become more accurate and faster. Recovery Very basically, this means digging up the target. On farm fields and on beaches this entails extracting the target from the soil/sand with a small/medium trowel, taking care to reinstate the disturbed ground after recovery. However, it is especially important when working on an amenity or cut grass sites to remove your targets and to restore the areas around your finds without leaving a mess. Use a straight-edged trowel to cut a neat plug with three or four edges approximately 200mm long. Cut the plug with sloping sides to help its keying when you replace it. Lift out the plug, invert it and place it on a piece of cloth. Remove the find from the hole, then loosen up the soil in the bottom of the hole. Align the plug correctly when refitting it, then re-firm the ground with your foot. Score the surface of the plug so that the cut edges will quickly knit together again. Any soil remaining on the surface should be brushed into the grass with your gloved hand. Place any scrap metal or sharp objects in your junk bag for safe disposal later.

By simplifying features and complicated adjustments that cause a loss of performance when used improperly, Laser has created an easy to operate, grab-and-go detector that s perfect for hobby, sport and travel. The Rapier II is a Transmitter-Receiver (TR) type detector that operates in the Very Low Frequency (VLF) portion of the Radio Frequency (RF) spectrum. The detector uses only three control knobs, a switch and push-button to provide full VLF capabilities. The performance of the Rapier II will satisfy the requirements of the serious detectorist, whether experienced or a beginner. The Rapier II uses the latest Surface Mount Technology and Laser s proven circuitry to create one of the most unique Printed Circuit Boards in the industry. This circuit board helps provide greater depth and more sensitivity to small, less conductive metal objects or targets such as fine gold jewelry. The Rapier II has features that make its power easy to use. The factory preset ground rejection circuitry allows turn-on-and-go operation in virtually any ground mineralization * The Discriminate Mode is Silent Search, meaning the searchcoil must be moving to detect a target. The QuickChick Pinpointing makes it simple to identify the exact location of the target. The electronic miniaturization of Surface Mount Technology permits the complex powerful circuitry of the Rapier detector to fit into a very small space. The result is a detector that is so incredibly light there is no need to body mount the control housing. This exclusive design features adds to the Rapier s ease of use and makes those longer searches more enjoyable. The Rapier II comes with an 9 x8 round concentric searchcoil for best all-around performance with good depth. A variety of optional Rapier searchcoils are also available and will enhance the detector s performance under various conditions. *Operation may be more difficult in black sand or certain other extreme ground conditions. 5

8 6 LASER RAPIER II OPERATOR INSTRUCTION MANUAL GETTING STARTED UNPACKING THE BOX Your Rapier II was shipped with these parts: 1 Upper Pole Assembly Fully assembled, including upper pole stem with handle grip, padded arm bracket and control housing. 1 Middle Pole Assembly With Pole Lock 1 Lower Pole Assemby Fully assembled with nylon pole tip complete with two friction washers, wingbolt, and thumb nut. 1 9 x8 round concentric searchcoil with 3 cable 1 9-volt alkaline battery 1 Operator Instruction Manual If any of these items are missing, contact the Laser Authorized Dealer where you purchased your detector immediately. Assembly of the Rapier II is simple and requires no special tools. Just install the battery, mount the searchcoil on the lower pole assembly, connect the two pole assemblies together, wrap the excess cable around the pole and plug the cable into the control housing. Finally, adjust the pole length and searchcoil angle and you re ready! Pinpoint Mode and check the target response sound. If the response is weak, it may well be a deep, good target. But if the response is very strong, it is probably trash. Note that a coin close to the surface can give a double beep sound, but it is regular and repeatable. Raising the coil an inch or two will restore the single beep on surface targets. When searching in the Discriminate Mode, it is best not use a higher DISC LEVEL setting than necessary. Nickels and most smaller rings are rejected when the DISC LEVEL is set to reject pull tabs on any metal detector that is a TR Discriminator like the Rapier II. If you don t dig any junk at all, you are surely passing up a lot of good finds as well. Set the DISC LEVEL only high enough to suit the conditions where you are searching. If there is any doubt whether a target is good or not, dig it. Pinpointing a target OPERATING TECHNIQUES Pinpointing a target in Discriminate Mode is probably best done by X-ing as well. Remember that the detector will beep just as the target passes under the center of searchcoil Slowing the sweep speed down will help you pick out the center of the X because the target response is reduced at very slow speeds making it easier to correlate the sound with the coil center. Another easy method is to sweep the coil from side to side across the target in very short sweeps as you slowly move forward and backward across the target. Slow down the sweep rate and shorten the sweeps until you just barely get a response at one spot. The target will be directly below the coil center at this response time. Another method of pinpointing in Discriminate Mode is to quickly change to Pinpoint Mode to check the target response. Remember that Pinpoint Mode is not susceptible to the false signals of Discriminate Mode and can sometimes give a clearer and more consistent response to difficult targets such as a dime buried next to a pull tab. By switching back and forth between modes and comparing the target response sound in Pinpoint to the target response sound in Discriminate, you can often better identify the likely location of the target. The QuickCheck PINPOINT Push-button allows you to do this easily and without looking away from the ground at your controls. 19

9 18 LASER RAPIER II OPERATOR INSTRUCTION MANUAL GETTING STARTED In areas with well-kept lawns, the easiest way to maintain a constant searchcoil height is to allow the coil to rest on the grass as you sweep from side to side. In rough and rocky areas, it is best not to scrub the coil on the ground, as the rocks will act like abrasives, and wear away the coil bottom (an optional coil scuff cover will protect against this). Sweep the coil as close to the ground as possible without touching. Hitting the ground or rocks may cause a false signal much like a desired target would. Sweeping the coil too high above the ground results in a loss of depth. INSTALLING THE BATTERY Your Rapier II is equipped with an automatic battery test circuit so that you can always be sure you are getting top performance. The battery should be checked after the detector has been on for about 10 minutes, and then periodically when used for long durations. For more detailed information turn to Performing the Audio Battery Test on page Planting a Test Garden To learn better how your detector will perform in the field, it would be helpful to bury some coins and trash metal junk items in an area that you know is clear of other metal objects. Check the area with Disc set at zero to be sure it s clear of trash, then bury the targets at least 1 foot apart, and from 2 to 4 inches deep to start. Make a map of the area to be sure you know what each target is and how deep it is. Practice on these targets to familiarize yourself with your detector s target response. This will also help you learn the proper sweep speed for best operation. This type of practice area is often called a test garden or test bed and is one of best tools to help you develop your metal detecting skills. Recognizing false signals in Discriminate Mode When operating in the Discriminate Mode, some false signals may be caused by 1) heavy concentrations of trash metal objects, 2) very large trash metal objects, or 3) electrical interference. These signals are generally short, choppy sounds and sound different than good signals (good target response sounds). At the end of your sweep, as you reverse the coil direction, the detector is most susceptible to trash induced noise. There are two ways to tell whether these sounds are good deep signals or trash noise. The first is by repeatability. Trash induced noises will not be regular as you sweep the coil over the suspected target several times, Whereas a good target response will be repeatable. The second method is to switch to To install or replace the battery, first make sure the SENSITIV- ITY control is set to POWER OFF-turned completely counterclockwise past the click. Remove the battery door from the back of the control housing. Do this by pressing your thumb firmly on the louvered squareat the bottom of the battery door-and sliding the battery door upward (in the direction of the arrow) while pushing. Check the polarity on the battery and on the diagram inside the battery compartement. Make sure that they match and simply drop a fresh 9-volt alkaline battery into the compartment.

10 8 LASER RAPIER II OPERATOR INSTRUCTION MANUAL ASSEMBLING YOUR DETECTOR 1) On the lower pole assembly, remove the mounting screw and thumb nut from the black nylon pole tip. 2) Insert the pole tip between the mounting ears of the searchcoil and align the holes of the pole tip and washers with those of the mounting ears. NOTE: the pole tip should fit very snugly unto the mounting ears; however, it may be necessary to use the thin friction washers instead. 3) Insert the mounting screw through the holes in the mounting ears and pole tip-entering from the side opposite the cable connection. 4) Install the thumb nut on the mounting screw and tighten by hand. (NOTE: Do not overtighten the thumb nut. It should be snug, but not too difficult to loosen up.) 5) On the upper pole assembly, depress the two spring buttons and slide the middle pole assembly into the upper pole assembly until the spring buttons click into the hole-locking the two assemblies into place. Tighten the pole lock to secure the two assemblies together. Performing the Audio Battery Test Your Rapier II is equipped with an automatic battery test circuit so that you can always be sure you are getting top performance from it. The battery should be checked after the detector has been on for about 10 minutes and then periodically if you are using it for long periods. To activate the Audio Battery Test, simply turn the detector off momentarily and then back on again. If the battery is fresh, the detector should emit a continuous and loud beep sound that lasts for about 4 or 5 seconds, and then slowly fades into silence. As the battery ages, this sound is less intense and fades out more quickly. When you hear only a brief buzz or no sound at all, replace the battery with a fresh one. If you prefer, a rechargeable Nickel-Cadmium (Ni-Cad) battery can be substituted for the standard 9 volt alkaline battery. Individual 9 volt size Ni-Cad cells, as well as the chargers for them, are readily available at most electronic supply stores. They are installed into your detector in the same manner as non-rechargeable batteries. The battery test sound on a Ni-Cad will be weaker than an alkaline in the beginning, but will not weaken as much with use. FIELD USE Handling your detector OPERATING TECHNIQUES The detector should be held in a position that is comfortable for you as shown in the ADJUSTING THE POLE & SEARCHCOIL section in a three foot arc, overlapping succeeding strokes well. This motion is called a sweep. The Rapier II was designed to get maximum depth without the frantic pace required of earlier motion detectors, so go at a pace that is comfortable for you. In fact, trying to hunt too fast may even cause a loss of depth in heavily mineralized locations. Regardless of which mode you are using, try to keep your searchcoil height constant and close to the ground. Most people tend to raise the coil at the end of the sweep-much like a pendulum-especially if they are hurrying. Try to avoid this, as any increase in height from the ground will cause a corresponding loss of depth. 17

11 16 LASER RAPIER II OPERATOR INSTRUCTION MANUAL GETTING STARTED 9 The DISC LEVEL should be set to your desired rejection level for the particular area you are searching. We recommend starting at a low setting if you are unsure of how much trash is in the area. Adjust the level higher if you find yourself digging more trash than you like. Remember that with any metal detector, you will lose target response to small gold rings and nickels when discrimination is set at the pull-tab rejection level. So, digging some trash will increase your number of good finds. The diagram DISC LEVEL- Discrimination Level Settings shows the settings where many of the common metal objects are ignored by a typical detector. Each detector can vary a little due to manufacturing tolerances- so you should experiment with your detector and become familiar with its rejection levels for these trash metal objects. Earlier motion detectors that operated with a continueous threshold sound would give the user a definite indication of trash metal by either nulling completely (no sound made temporarily) or by generating short, choppy sounds. Since the Rapier s Discriminate Mode is Silent Search and operates without threshold sound, there is no nulling to indicate that the area is extremely trashy. When searching in the discriminate Mode, we recommend that you periodically switch to Pinpoint Mode and check the area your are searching to get an idea of how much trash is really there. Setting the Threshold Level The Threshold Level must be set so that the sound that you hear in the pinpoint mode is a low volume, steady hum. To start, press the PINPOINT push-button and listen for the threshold sound. Adjust the Threshold Level by turing the THRESHOLD control. To increase Threshold Level, turn the control clockwise. To decrease, turn the control counterclockwise. Adjust the control until the low steady hum is achieved and release the PINPOINT push-button. Once the desired tone is set, it will not require frequent resetting. 6) Slide lower pole into middle pole until spring buttons click into the first set of adjustment holes. Turn pole lock to tighten-lock the assembly into place. 7) Wrap the cable around the pole leaving enough slack near the searchcoil to permit searchcoil adjustment. (NOTE: Do not allow the cable to flop loosely over the searchcoil. Since the detector is sensitive enough to see the tiny wires in the cable, a floppy cable can cause false signals as the searchcoil senses the moving wires. 8) Plug the male cable end into the female connector on the control housing and tighten the cable thumb nut. You are finished! (NOTE: You will want to adjust the pole length and the searchcoil angle to your preference.

12 10 LASER RAPIER II OPERATOR INSTRUCTION MANUAL OPERATING TECHNIQUES 15 ADJUSTING THE POLE & SEARCHCOIL The pole length should be adjusted so that the detector does not become uncomfortable or tiring after long periods of use. The detector grip should rest in your hand with your arm relaxed, your elbow straight but not locked, with the pole extending out in front of you at the approximate angle shown in the photo. You should be able to swing the detector back and forth in front of - using relaxed shoulder movement - while keeping the searchcoil as close to the ground as possible. This swinging movement is often called a sweep. The searchcoil should not touch the ground during your sweep. The pole length should be adjusted to allow this without having to lift the detector with your elbow or shoulder. The searchcoil should rest about one inch above the ground while you are standing erect. The angle of the searchcoil should allow the bottom to be parallel to the ground. The pole length is adjusted by depressing the spring buttons and extending or shortening the pole until the spring buttons click into the set of holes that give you the most comfortable pole length. To adjust the searchcoil angle, simply loosen the searchcoil thumb nut slightly and move the searchcoil into the desired position. Tighten the searchcoil thumb nut by hand so that the searchcoil will hold in place. Setting the Sensitivity Level in MAXBoost The MAXBoost feature is a high gain boost over and above the normal maximum of 10 and is indicated by the red area on the SENSI- TIVITY control. Using MAXBoost will cause no harm to your detector, but in certain conditions, it can result in the annoying chirping sound that may make if difficult to hear a good target response sound. In ideal conditions, MAXBoost can add inches of depth to your search with no chirping. In difficult conditions, the extra depth will still be there but heavy chirping may make the feature too difficult to use. You must determine when and how much of the MAXBoost feature to use for your search site conditions. Setting Discrimination Level The DISC LEVEL control is used to adjust the detector s response to unwanted trash metal when operating in the Discriminate Mode. At the lowest setting (MIN), the detector will ignore most small iron objects, but will still respond to light foil, bottle caps, pull-tabs and most other metal objects. As the Discrimination Level is increased, more of these trash metal objects are ignored and give no target response sound when inside the searchcoil s range.

13 14 LASER RAPIER II OPERATOR INSTRUCTION MANUAL OPERATING TECHNIQUES 11 TUNING YOUR DETECTOR Since the most troublesome adjustments of standard detectors have been automated in the Rapier II, Tuning this detector is simply a matter of: ➊ Setting the Sensitivity level using the SENSITIVITY control. ➋ Setting the Discrimination level using the DISC LEVEL control. ➌ Setting the Threshold level using the THRESHOLD and PINPOINT control. Selecting the Proper Operating Mode The Rapier II offers two operating modes, Discriminate Mode and Pinpoint mode. Both modes are also mineral free. This means the detector s circuitry has been factory preset to ignore all but the most extreme ground mineral conditions. The Discriminate Mode is Silent Search. This means that the detector will make no sound until it encounters a metal target. This mode requires that the searchcoil be slightly in motion for target detection. The Pinpoin mode is threshold based. This means the detector has a baseline hum, set by the threshold control, that will get louder when it encounters any metal target. If the coil stops moving, the target will be tuned out. The Pinpoint mode provides simpler information than the DISC mode. For more infomation on pinpointing see page 19. OPERATING TECHNIQUES CONTROLS The Rapier II has only five controls, all mounted on the front panel of the housing for fingertip adjustment. How these controls should be set for peak performance will depend on the type of metal you are searching for, search site conditions, and so forth. Use the information in this section and the TUNING YOUR DETECTOR section as a basis for setting the controls on your detector. Using your detector in the field will allow you to learn fine tuning the detector s operating controls SENSITIVITY Sensitivity Control PINPOINT QuickCheck Pinpoint Push-button DISC LEVEL Discrimination Level Control THRESHOLD Threshold Level Control Setting the Sensitivity Level In lightly to moderately mineralized ground, you can usually set the SENSITIVITY control as high as 8 to 10 (normal maximum setting). In the right conditions, you can move the SENSITIVITY control clockwise as far as possible until the detector just begins to chirp Intermittently. If the chirping is too frequent, simply turn the control counterclockwise just enough to cause the chirping to subside. Once set, this control should not require readjusting unless site conditions change. Occasionally, you may need to reduce the setting to eliminate false signals casued by difficult conditions such as highly mineralized ground on trashy sites or nearby sources of electrical interference. These false signals are generally short, choppy sounds that can be easily distinguished from a good target response sound. Extreme conditions such as wet salt sand may require you to lower your sensitivity setting into the 2 to 5 range. TONE Tone Selection SENSITIVITY ON/OFF-Battery Test Sensitivity Control As its name suggests, this is in fact a three-function control: First, it is used to turn the power on and off. Rotating it clockwise past the an initial click turns the detector on. Rotating it fully counterclockwise until it clicks disconnects the batteries from the circuit, turning the detector off. Secondly it activates an automatic battery test when the detector is first turned on. (NOTE: This test should be performed with the Mode switch in the Discriminate position.)

14 12 LASER RAPIER II OPERATOR INSTRUCTION MANUAL OPERATING TECHNIQUES If the batteries are satisfactory, there will be a loud tone gradually fading to silence over 3 to 5 seconds. The fresher the batteries, the louder the tone. When the tone becomes weak and brief, or there is no sound at all, it is time to replace the batteries. Always fit 9 volt alkaline batteries. Third, it is used to adjust the detector s sensitivitiy. The recommended setting for most conditions is around 9-10 on the scale. On occasion you may need to reduce this to eliminate false signals when encountering difficult conditions, i.e., highly mineralized ground on junk infested sites. Wet salt sand may require you to drop to between 2-5 sensitivity. Your Rapier incorporates a high gain boost over and above normal maximum of 10. This is indicated by a red section on the scale. Entering this setting will cause no harm to the unit, but may very well cause instability. The boost section will give increased performance only if conditions are ideal, so we would advise caution in its use. may also need to change tone based on field condition, such as traffic noise, wind noise, flow water, ect. THRESHOLD Threshold Level Control This rotary control has one function: Adjusts the Threshold Control The THRESHOLD control is used to adjust the audio level of the detector s threshold up or down to its desired level. Normal setting would be a barely audible hum. This is not a volume control for the detector itself. Although this control is placed on the front panel for convenience, once it is set to the desired threshold tone, it will not require frequent resetting. 13 DISC LEVEL Discrimination Level Control This rotary control has one function: Adjusts the Discrimination Level While the detector is in the Discriminate Mode, the DISC LEVEL control is used to adjust the detector s Discrimination Level. Turning the DISC LEVEL knob clockwise increases the detector s Discrimination Level and vice versa. TONE Audio Tone Selection Switch This switch has one function: Select the Audio Tone The TONE switch is used to select the audio tone for the detector. Selecting LOW will give the audio a lower tone. Selecting HIGH will give the auido a higher tone. This will affect the detectors tone in Discrimination mode, Pinpoint mode, and the Battery Test. Select the audio which bests works for your conditions. Check both modes with a small target to see which tone you hear better. You PINPOINT QuickCheck Pinpointing Push-button This push-button control has two functions: Places the detector in Pinpoint Metal Mode Adjusts the Threshold sound When the detector is in the Discriminate Mode, the PINPOINT push-button is used to momentarily change the operating mode for improved pinpointing. Pressing the push-button places the detector in Pinpoint Mode. The detector remains in Pinpoint as long as the push-button is held down. Releasing the push-button returns the detector to Discriminate Mode. Pinpoint push-button must be held to adjust the threshold. Controlling Audio Volume The speaker in the Rapier II does not have a volume control. The volume should be sufficient to accurately hear the target response sound in most environments. If more or less volume is required in your particular situation, we recommend using a set of good quality headphones with a built-in volume control.
